SIEM – Security Information and Event Management

Analyze data from every corner of your infrastructure.

The ITH SIEM system collects data from various sources—servers, network devices, applications, and endpoints—correlates security events, and delivers real-time security alerts. Continuous monitoring rather than reacting after the fact.

What is SIEM, and why is it a key component of cybersecurity?

Security Information and Event Management (SIEM) is a solution that combines two key areas of IT security management: security information management (collection and storage of logs) and security event management (real-time analysis and correlation of events).

SIEM software collects data from various sources simultaneously—including firewalls, servers, databases, applications, network devices, and endpoints—and analyzes large volumes of data to identify patterns that indicate potential threats. With SIEM, security professionals gain a single, unified dashboard for managing IT security across the entire organization.

A SIEM system is a key component of modern cybersecurity strategies, especially for large enterprises operating complex infrastructure, where manually analyzing logs from dozens of systems is physically impossible.

How does a SIEM system work?

SIEM collects, correlates, and responds in real time
1. Data Collection

SIEM collects data from various sources: servers, network devices, applications, databases, endpoints , and the cloud. Data is collected using agents.

2. Normalization and Parsing

Data from various data sources comes in different formats. The SIEM system normalizes this data into a unified model, which enables the effective detection of relationships between events from different systems.

3. Correlation of events

SIEM analyzes data to identify patterns of event correlations. Machine learning and artificial intelligence make it possible to identify suspicious behavior that would not be apparent if each log were analyzed individually.

4. Alerts and Prioritization

When the SIEM system detects an anomaly, it generates security alerts with priorities based on context. Thanks to , security teams are not overwhelmed by thousands of false positives.

5. Reporting and Compliance

SIEM software generates detailed reports to meet regulatory requirements, support audits, and facilitate IT security management. Reporting is tailored to NIS-2, ISO 27001, and GDPR.

Regulations and Compliance

A SIEM System as the Foundation for Compliance with the NIS2 Directive

The NIS2 Directive requires organizations within its scope to, among other things, continuously monitor incidents, have documented response procedures, and report security incidents within strictly defined timeframes. ITH’s SIEM solution provides the tools necessary to meet these requirements without having to build the entire infrastructure from scratch.

  • Continuous monitoring and logging of security events in accordance with NIS2
  • Detailed incident reports ready for submission to the CSIRT
  • Log retention and documentation of user activity required by regulatory requirements
  • IT security management with a full audit trail, ready for inspection by regulatory authorities

Data Sources

SIEM collects data from your organization's entire ecosystem

Every organization's IT system generates thousands of events every day. Siem collects and analyzes data from various sources simultaneously, eliminating the need to manually analyze each log.

1.

Servers and Operating Systems

System logs from Windows and Linux servers—user activity, privilege escalations, and process anomalies.

2.

Network Devices and Firewalls

Analysis of network traffic, IP addresses, access attempts, and blocking—threat detection at the network level.

3.

Databases and Business Applications

Monitoring access to databases and critical applications – data breaches and unauthorized access are detected immediately.

4.

Endpoints and workstations

Endpoint data—malware, suspicious user behavior, unauthorized devices on the network.

5.

Cloud and SaaS Services

Continuous monitoring of hybrid and multi-cloud environments.

6.

Other security tools

SIEM integrates with EDR, IDS/IPS, WAF, and other security tools, centralizing data from the entire security ecosystem.

SIEM + SOC = Comprehensive Protection for Your Organization

A SIEM system is a technology. A Security Operations Center (SOC) consists of people and processes that operate based on data from the SIEM. Combining a SIEM solution with ITH’s SOC service creates a complete IT security management ecosystem—from data collection to immediate 24/7 incident response.

    FAQ

    Standard logging systems collect and store logs. A SIEM system does much more—it analyzes data, correlates events from various data sources in real time, uses machine learning to detect suspicious behavior, and generates prioritized security alerts. With SIEM, cybersecurity professionals gain context and insight, not just raw data.

    No. Traditionally, SIEM solutions have been associated with large enterprises due to high licensing and implementation costs. ITH’s managed SIEM model eliminates these barriers; the organization pays for the service, not the infrastructure. This makes the SIEM system accessible to companies in any sector subject to NIS2 requirements or other security regulations.

    NIS2 requires continuous monitoring of security incidents, reporting them within strictly defined deadlines, and retaining incident documentation. SIEM software automatically logs all security events, generates detailed reports in an audit-ready format, and maintains long-term log retention. Learn more about NIS2 requirements at ith.eu/wdrozenie-nis-2 and ith.eu/nis2.

    Implementing your own SIEM system involves purchasing licenses, building infrastructure, hiring cybersecurity specialists, and continuously managing the platform—a cost of several hundred thousand zlotys per year. ITH Managed SIEM is a service-based model: we provide SIEM software, infrastructure, implementation, and support as part of a monthly subscription. There’s no need to invest in your own resources, and no risk of gaps in IT security management.

    We collect only security logs (events, network metadata, alerts)—not message content or business data. The data is stored on ITH servers located in Poland, in accordance with the GDPR and a data processing agreement.
